Orlando, I just wanted to know if the practice existed in Brazil, and, if so, what it was called. I spent 30 years in the criminal justice system in California, and I saw it used there. We have an expression that goes "The defendant who defends himself has a fool for a client" (also "The doctor who treats himself has a fool for a patient.'). I think sometimes people go "pro per" out of boredom or because it allows them greater freedom of movement (they have to go to the jail law library, right?). In other situations, they are simply willing to try anything to get out of jail.
